BRU Tapes on Unix?

Hi, Friends of mine have an old, not that much DEC compatible PDP11 like machine that they (and me) would get working again. The machine is located at the German Chemical Museum in Merseburg. http://www.robotrontechnik.de/index.htm?/html/computer/k1600.htm Scroll down to the K1630. The Machine was rescued from the old power plant in Thierbach before. It is an PDP11 build out of some east german 8 Bit Bitslice CPU's and has 248K Ram. They used an unusual BUS, an Z80 Sio for The console (this is really ugly) und Bus communication controllers on each peripheral board that must be configured before the first use of that board, this means the IO Adress, DMA Registers, Modes and Vector addresses are set in Software before the Processor can talk to them like in a PDP11, so every DEC-OS must be patched to work on this thing. It is a slow machine too :-) We now have some CPTP Dumps of BRU Backup Tapes of the Operating System OMOS for this machine (old version of RSX11) I have a copy here http://www.tiffe.de/Robotron/K1630 There are 2 Versions omos-sys.tape.gz is the original type file in CPTP Format, omossys.tap.gz is the same thing converted with taput to simh tape format. Same with the dok tape, the docs are in german... My friend Oleg told me that the tape files are broken, may be this is the fault of taput (http://www.mrynet.com/hp2000/taput/index.html). My question is if somebody can verify what is going on with the files and if an opensource utility exists that can read BRU files on unix (like my FreeBSD here).... I think the OMOS-SYS Tape is the only real chance to boot this thing sometime again.. Kind Regards, Holm -- Technik Service u.
